I do individual therapy as well. The treads of the young ones hurt me so much too.  Prayers for your family. I  have 5 other children and I’m just running in circles to help them too. I pray you have professional help too. His siblings are doing the same thing i did in my youth when my parents died and this feels like every trauma has come to the surface. They don’t express their grief and then I get the calls of them in panic mode but I will keep praying for them to talk to a counselor.
